This includes support for hosting onion services, and connecting to them, which are two separate things:
- Opening an onion service implie interacting with the tor daemon controller, which requires authentication. We support both `SAFECOOKIE` and `HASHEDPASSWORD` authentication mechanisms, with a default to `SAFECOOKIE`. We support v2 and v3 services, with a default to v3 as recommended by the tor project.
- Connecting to onion services requires tunnelling through tor's local SOCKS5 proxy.
Incoming and outgoing tor connections are thus separate matters that needs to be configured independently. A specific documentation has been added to guide users through these steps.
Big thanks to @rorp for doing the heavy lifting on all this!
